Application filed November 2, 1906. Serial No. 342,937.

vention which follows, reference is inadc to the accompanying drawings forming apart hereof, and in which,'

Figure 1 is a partly sectional side elevation of the improved labeling machine, and Fig. 2 is a plan view of thesame. Figs. 3, 4, 5 and 6 are enlarged details of the machine as illustrated in Figs. 1 and 2, and hereinafter described. Fig. 7 is a view similar to .Fig. 1, illustrating certain modifications in the construction of the machine, and Fig. 8 a plan of Fig. 7. Figs. 9, 10, 11 and 12 are enlarged views of details of the-machine, as illustrated in Figs. 7 and 8, and hereinafter described. Fig.13 is a transverse view 'of parts ofthe machine'shown-in Figs. 7 and 8 and on the same scale.

Referring now to Figsd l to -6, inclusive, of the drawing, 1 is vthe frame of the machine,

' and a, a are the legs thereof.

The runwavwhereby the unlabeled cans are delivered to the'labeling ap liancesof the machine is denoted by 2, an therunway which carries away the labeled cans is represented by 3. A'star wheel4 on a shaft 5, rotated by mechanism hereinafter described, serves to produce an intermittent delivery ofcans from the runway 2 to the label-applying de-,

vices.

7 and 8 are sprocket-wheels secured to horizontal shafts 9 and 10. respectively, carrying the endless sprocket/ chain 12. The sprocket chain 12 is provided with carriers 13 to which the cans are delivered from the runway 2. v

15 is the driving shaft of the machine, from which motion is communicated to the shaft 10 of the sprocket wheel 8 by means of the sprocket wheels 17 and 13 and the chain 19. J

'lhc shaft 9 is provided with a sprocket wheel 20 and the'sliaft 5 with a similar wheel .machine. 7

newly applied labels tightly to the cafe Fig.1.

ing chain 12 is in motion the star wheel 4 is in rotation.

23, 24 and 25 are vertical shafts situated at one side of the frame 1, adapted to rotate in suitable bearings, andto theseshafts res ectively, are fastened the heads 26, 27 an 29, each one of which has a separate and distinct function to perform.-

Each of the heads just referred to has four arms (1 and the arms of the head 26 are for the purpose of applying paste to the headsof can's, while those of the head 27 carry labels in stacks and deliver the labels singly to the pasted head of the cans as they traverse the The arms of the head 29 press the heads.

The shafts 23, 24 and 25 are rotated at a uniform speed by'the miter gears c and f, the formerbeing on the said shafts, and the latter on the horizontal shaft 30 which derives its movement from the driving shaft 15 by means of the'spiral pinion 32, and its spiral wheel 33 which is. on the shaft 30.

The arms d of the head 26 have cylindrical faces (see Fig. 4) formed of some soft material such as sponge rubber, and they receive paste from the box 35 through the medium of two frusto-conical rollers 37 and 38 which receive their motion from the shaft 23 by a suitable train of gearing as is well shown in The rollers 37 and 38 may have surfaces of any approved description, but it is believed that the latter which rotates in the body of paste should be fluted, and the former knurled as shown in Fig. 1.

The arms (1 of the head 27 are bored and sharp blades which as the top olouter label is detached, cuts through the paper. By

. knurling the stems h the friction between them and the edge ofthe stack of labels is in creased, which has the effect of preventing the dislodgmcnt of more than one label at a time. r

The proper curvature of the stack of labels is further preserved by the additional stein la (see Fig. 6) which are provided with sp; mg

when not being operated upon as described.

When the machine is in operation, a can passing from the runway 2 to the runway 3 reef-zines a coating of paste from an arm of the first head 26 which adapts it upon reaching the second rotary head 27 to detach a label from a stack. When the can reaches the third andlast head 29, the label is firmly pressed in contact with the can head.

In the operation of the machine just described one head only of the cans is provided with a label, and should it be required to label both heads ofthe cans they can be put through the machine a second time in a reversed position; or the label affixing devices described could be duplicated in the machine,

the second set being substituted for the abutments 40.

In the foregoing, the machine has been described as adapted to apply paste to the cans, but as paste requires a considerable time to dry, and until dry, has little' adhesive qualities, I propose to ada t the machine to use an adhesive which isiquefied by heat and applied hot to the can heads. I also propose to substitute for the cylindrical faces of the arms (1 of the head 26, hot cement-applying mechanism Which Will adapt itself to any inequality in the surfaces of the can heads, or

apply the cement to the can heads by a multiplicity of independent stems. I also proose to provide the abutment opposite to the liead 27 with an endwise movement towards the can, at the moment that a stack of labels is brought into a plying position, in order that the can may e forced into contact with the outside label or the label to be taken from.

the stack. I also pro ose to confine the spring-held stack of la els in a cyhndrical casing or shell, and provide the inner surface of the said casing with devices whereby the labels are curved so as to present a cylindrical surface to the can heads lndependently of such surface being affected by the curva-' ture of the plunger 39 which serves to move the entire stack forward or towards the cans. The modifications above briefly referred to are shown in Figs. 7 to 13, inelusive vhich will now be fully described.

Referring to Figs. 9 and 10, it .will be seen that instead of the construction of the arms;

(Z of the head 26 shown in Figs. 1, 2 and 4, they are made with flat ends and provided with circular plates d spaced from the said ends, and held in place by bolts (1. Supported by the arms and the circular plates d, and adapted to have a yielding longitudinal movement, are the stemsf the rounded ends of which are anointed with heat-lique- -lied cement by means of a disk 9 arranged to be rotated in a suitable vessel 71. shown in Figs. 7 and 8. The cement may be heated by any available means and preferably by electricity.

Referring to Figs. 11 and 12, it will be seen that the stack of labels is confined in a cylindrical casing 0r shell is instead of between the knurled stems 7: shown particularly in Fig. 5, and the curvature of the labels independently of that produced by the s )ring-backed plunger 39 is effected by the hxed inclined strips m. The cylindrical shell 1c is removable in order that a stack of labels may be inserted therein from the rear of the shell, the plunger 39 being held back at the time by means of a pin a which is made to enter the lateral extension of the slot 0 The pressing of a can against the outer label of the stack, befo e briefly referred to, is produced by the mechanism illustrated in Figs. 7, 8 and 13, and consists in securing the 9,,

abutment-40 opposite the label-allixing head 24, we spring-held longitudinally-nioving stem 41. which is forced inward as a can is brou ht into labeling position, primarily by the s aft 24 through the means of a disk 43 havingstuds on its edge which strike one end of.a' sliding rod carrying at each end a roller, and a pivoted cross-arm 45 against which the other end of the sliding rod is in contact as shown particularly in Fig. 13. It is however within the scope of my invention to employ entirely different means to effect the motion of the abutment 40, and push the cans closely in contact with the stack of labels as described.

I claim as my invention 1. In a can labeling machine, an entrance runway having a device to intermittingly discharge cans therefrom, an endless continuously moving chain with carriers to receive the cans and convey them longitudinally of the machine, and a delivery runway to which the cans are delivered by the endless chain, combined with devices situated between the two runways to paste the head of a can, apply a labelto the pasted surface of the can, and then press the applied label tightly to the can head, the three 0 )crations being pergormed in sequence, su'stantially as speci- 2. In a can labeling machine, an entraiwc runway having a device to intermittingly discharge cans therefrom, an endless movin r chain with carriers to receive the cans and convey them longitudinally of the machine,

, and a delivery runway to which the cans are delivered by the endless-chain, combined with a rotary head provided witharms'each of which is adapted to come into contact with the head of a can as it passes the rotary head, a paste receptacle,-means totransfer paste from the paste receptacle to the said arms, and other meansv to apply a label'to the pasted surface of the can, substantially 10 and a delivery runway to which the cans are delivered by the endless chain, combined with a rotary head provided with arms each one of which is adapted to come into contact I 0 with the head of a- 'can as it passes the rotary head, a paste receptacle, meansto transferpaste from the rece tacle to the said arms, other means to app y a label to the pasted surface of the can, and devices to subsequently press the applied label to the can head, substantially as specified.

4. In a can labeling machine, an entrance runway having devices to intermittingly discharge cans therefrom, an endless chaln with carriers to receive the cans and convey them longitudinally of the machine, and a delivery runway to receive the cans from the endless chain, combined with devices to apply paste to the can heads while the same are in motion, other devices to apply labels to the pasted surfaces of the cans, and means to press the applied labels to the can heads,

substantially as specified.
